Chris Kerr's Human-Actuated Robotic Gripper -- George School

For his winter term final project, my student Chris Kerr wrote a simple BasicX application that opened and closed a robotic hand as he opened and closed his own hand. The robotic hand is the Gripper from Robodyssey Systems. The actuator is a plastic conducting strip whose resistance changes as the strip is bent. (I purchased this flex sensor from Jameco (www.jameco.com P/N 150551) for about $13.) The BX-24 brain detects when Chris bends the strip via a voltage divider board (VDB) from Robodyssey. Chris did a nice calibration job matching the bending of the strip to the Gripper motion. Chris' project has innumerable practical applications!

Robodyssey Systems manufactures the RAMB II motherboard you see here. The robot's brain is NetMedia's BX-24 microcontroller, which is programmed using the BasicX language. I am the author of the world's only BasicX textbook; if you are interested in learning how to program your own robot, see my website at www.basicxandrobotics.com.

Sir I am a final year Electronics student pursuing my degree of B.E. I have planned to make a robotic arm for my final year project. I saw your work and was truly amazed.I know you must be very busy with your work.But it would be a favour if you can guide me as in how to go on sequentially to implement this project.I've seen many of such gloves but dis project of urs has inspired me 2 go for it myself. So I'ld really appreaciate if you can enlighten me as to how 2 make it possible Thank you.

Hi. Expand the summary block under my video for more details. All the BX-24 does is read the resistance of the flex sensor. (It actually does this by translating this to a voltage and reading the voltage from a voltage divider board. When it detects the sensor is bent, it sends a signal to the servomotor-driven gripper which closes an appropriate amount. This is explained in detal in my book, "BasicX and Robotics" which can be purchased from lots of places including Robodyssey Systems.

Well done!

Followed by you introduction.I used the same sensor in my robotic hand.

Thank you very much!

Please have a look at my video.

Hi. I am glad our simple demonstration was a help to you and your fantastic robotic hand. Your work is fantastic! Thanks for the post.

It's so great, and can you tell me what kind of sensor are you using? congratulations

Hi. If you click on the "more info" link on the upper right side of the screen, you can read all about Chris's project and the sensor's vendor and part number (Jameco, 150551, $13). Glad you liked the video!

My name is Chris Kerr too! :D

4th comment yeah

Chris Odom, my teacher Mr. Peins always talks about Robodyssey and mentions you. We are working on getting our pic powered robots to follow lines right now. nice vid.

I like it man! I've just finished a new conceptual Robotic Gripper for a Wheelchair Mounted Robotic Arm!
